Pros: The RMA process works, I'm going through it again. I'm putting the lifetime warranty to use.

Cons: Need to pay shipping for each RMA. Both my original card and the card from the RMA died (the RMA one in less than 2 weeks). They aren't holding up in my basic phone (Motorola Moto E) very well. I had heard that KitKat was brutal to SD cards, but didn't think it would be this bad. Maybe the third time will be the charm?

Overall Review: I've got G-Skill RAM in my desktop PC and never had an issue. I'm not sure why the micro SD cards are so unreliable.
